Introduction to classical sinusoidal vibration

This book introduces the simplest of all vibrations …… sinusoidal, single-frequency-at-a-time vibration that doesn’t exist in the “real world” of automobiles, farm machinery, airplanes.

Not even in calibration laboratories, where waveform purity is highly valued. Even there you can measure some distortion. Not on machines. Not on vehicles. Even so, the concept of single-frequency-at-a-time sinusoidal vibration is useful. It keeps our math simple. It gives us a good “point of entry” into dynamics.

Many dictionaries define vibration in terms of this overly-simple (sinusoidal) form of vibration.
